AskUbuntu couldn't be more explicitly about Ubuntu, a specific Linux distribution. (Duh, right?)
With that in mind, should questions like this be renamed?
how to set up multiple IP addresses on my linux? ->
How to set up multiple IP addresses?
Set static IP address in Ubuntu ->
How to set static IP address?
Isn't there any search tool or trigger in the system to flag this kind of problems or others like Why are questions no longer titled as questions?
